PATENT \VILLIE F. SLACK, OF NORTHWOOD, NEW HAMPSHIRE.

DENTAL HEATER.

SPECIFICATION formingpart of Letters Patent No. 652,197, dated June 19, 1900. Application filed August 21,1899. Serial No. 727,879. (No model.)

To Ml whmn it may concern;

' tain new and useful Improvements in Dental Heaters, of which the following is a specification.

This invention relates to an apparatus for heating dental implements and materials; and it consists in the novel features of construction and arrangement, substantially as I shall now proceed to describe and claim.

Of the accompanying drawings, Figure 1 represents a side elevation of a dental heater constructed in accordance with my invention. Fig. 2 represents a plan View of the same with parts removed. Fig. 3 represents a plan view with the heating-pan or holderswung aside. Fig. 4 represents a section on the line at 4 of Fig. 2.

The same reference characters indicate the same parts in all the figures.

Referring to the drawings, a designates a flat base provided with a central recess or aperture to receivea spirit-lamp b for supplying theheat. Mounted on one edge of said base is a standard 0, which supports a heating shelf or holder d, the latter being composed, as shown, of a thickened-annular marginal portion or ring d and a thin central portion or plate (1 supported by a flange or annular shoulder d projecting inwardly from the inner edge of said ring. The shelf cl is loosely pivoted'on the standard 0 above the base a and adapted to be swung about the said standard. The lower end of the standard a is also preferably shouldered and fitted into a hole in the base a, so that the apparatus can be easily taken apart and packed in a small space. The central thin part or plate d of the shelf (1 may be utilized as a support, on which filling-gold may be annealed, guttapercha softened, dve, the burner of the spiritlamp 1) being ordinarily located immediately beneath the said plate (P, so that the latter will be raised to a temperature sufficiently high for the purposesnrentioned. The annular thickened portion d of the shelf 61 serves as a support for a number of dental articles and materials, substantially in the manner shown in the drawings. The ring d,

as shown, is formed at intervals with a series of holes, in which are fitted a series of vertical socket-pieces e e e 6 a thermometer f for indicating the temperature of the shelf, and a small metal on p g, adapted to hold medicated cotton or the like. The socket-pieces e e e are adapted to act as holders for variousimplements of dental use-sucl1 as a chip blower h, a syringe 'L', and a metal cup j for holding water or other liquid or for holding the receptacle containing the same. The small socket-piece 6 may be employed as a holder for drying out hypodermic needles.

The heat from the lamp 1) is conducted to the ring (1 and simultaneously to the metal socket-pieces, &c., held therein, so that the heating-chambers of the implements h i and the contents of the cups g j are kept in a heated condition ready for immediate use, the degree of heat being indicated by the thermometer f. The thickness of the ring cZ enables it to retain the heat received and to maintain an even temperature. The various articles supported by the ring at are or may be loosely'fitted in said ring, so as to be readily removable therefrom.

As seen in Fig. 3, the shelf of may be swung aside on its supporting-standard 0, so as to impart to portions of it or articles supported thereon a greaterdegree or less degree of heat than they normally receive, the flame of the lamp 1), for instance, being located immediately beneath the cupj in Fig. 3, so that the main part of the heat of the lamp is employed in heating the contents of the said cup.

From the foregoing description it will be noted that my improved apparatus is simple and convenient, and each article can be applied to or removed from it without disturbing any of the others. I do not confine my self to the precise details of construction herein set forth, as the same maybe varied without departing from the spirit of my invention. It is obvious that a gas-lamp or other lamp may be substituted for the. spirit-lamp b.

I claim- 1. A dental heater comprising a base, a standard mounted on one edge thereof, and a horizontal holder or shelf pivdtally mounted on said standard and supported thereby at or near its edge, said holder having individual holders for supporting a plurality of articles substantially equidistant from a heater vided with a plurality of holders, and a thin middle portion removably supported by said marginal portion.

4:. A dental heater comprising a base, a standard mounted thereon, a holder pivotally mounted on said standard, a series of socketpieces mounted on said holder, and one or more cups mounted on said holder.

In testimony whereof I have aflixed my signature in presence of two witnesses.
